The specification for Service Level 2 has been upgraded to include the NCC200 modules.

The NCC200s perform in a liquid, effortless manner whatever the musical programme is, be it rock, classical or intimately recorded solo performers.

During the work, the amplifiers are dismantled and every part is critically inspected - any doubt and it is renewed.

Particular attention is paid to the regulator assemblies which are thoroughly rebuilt using some very innovative techniques and components. The thermal trip system as fitted from new, is revised so as to no longer be a restrictive element in the mains supply but now operates in a totally transparent mode.

The main capacitors are replaced by Kendiel 22000uF caps.

Silence is now the name of he game and owners are delighted to find that the characteristic Naim background 'hiss' has all but disappeared.

These refinements add the final touch to the performance of these superb amplifiers - speed, agility, solidity - the list of plaudits goes on and on.

The Stage 2 NCC200 conversion has been equated by the lucky owners who have it, as being akin to the much more expensive Naim Audio NAP 300 so we're delighted to note that this complete revamp of the Naim flagship amplifiers give so much pleasure.

I just hooked up the modded 135 and the unmodded one, just for a bit of A-B comparative fun. Prior to the repairs and upgrades, it sounded similar, albeit distorted, compared to its twin. Now I’m speechless! The old 135 sounds like someone draped a blanket over the speaker. The NCC200 sounds better in every possible way: more grip, resolution, control, clarity, weight, depth, sparkle, speed. To say I’m stunned would be an understatement." - Permission to quote kindly given by Mike Hanson
